Proto J6345B Digital Torque Wrench 1/2 in Drive

Product Description

The PROTO J6345B is a digital torque wrench built for professional technicians who need precise, repeatable torque measurements in the field or shop. Fitted with a 1/2 inch drive and a fixed head, it covers a working range from 10 foot-pounds minimum up to 1,200 inch-pounds maximum, with a 1 Nm graduation and a resolution of 0.01 inch-pounds. At 22 inches overall length and 1.74 pounds, the J6345B is light enough for extended use without sacrificing the leverage needed for fastener-critical applications. HVAC, plumbing, and electrical trade professionals rely on calibrated torque tools wherever code or manufacturer specs require documented fastener torque values.

The J6345B is suited for residential and commercial service work where accurate torque application is required on compressor bolts, flange fasteners, panel hardware, and equipment mounting points. Its digital readout eliminates the guesswork associated with click-style or beam wrenches, making it a practical choice for technicians who document torque values during commissioning or maintenance. The 1/2 inch drive accepts standard sockets, broadening its usefulness across a wide range of fastener sizes encountered in mechanical and electrical installations.

Installation Notes

Torque wrenches should be used by qualified technicians familiar with the fastener torque specifications provided by the equipment manufacturer. Always consult the relevant service documentation before applying torque to critical fasteners. Store the wrench at its minimum torque setting after use to preserve calibration and spring tension. Periodic recalibration is recommended per the manufacturer's service interval guidelines.
